TRUCK-BEARING.

SPECIFICATION forming part of Letters Patent No. 789,072, dated May 2, 1905.

Application filed December 19, 1904. Serial No. 237,480.

To (all whom it may concern:

Be it known that I, WILLIAM H. SCOTT, a citizen of the United States, residing at Maplewood, St. Louis county, Missouri, have invented a certain new and useful Im rovement in Truck-Bearings, of which. the ollowing is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a fragmentary elevational view of a transom or body-bolster supported upon a carrier constructed in accordance with my invention, the truck-bolster being shown in section. Fig. 2 is a top plan view of a portion of the transom or body-bolster and truck-bolster, part of the transom or bodybolster being broken away. Fig. 3 is a View, partly in end elevation and partly in section, of the two bolsters and their cooperating parts, the section being taken on the line 3 3 of Fig. 1. Fig. 4 is a view, partly in section and partly in elevation, of a slightly-modified form of my invention. Fig. 5 is a to plan view of the same. Fig. 6 is a sectiona view on the line 6 6 of Fig. 4, and Fig. 7 is a side elevational view of a slightly-modified form of my invention.

This invention relates to railway-cars, and particularly to the truck for swingingly supporting the car-body.

The primary object of the invention is to provide means whereby the body-bolster or transom may have a transverse swinging movement independent of any movement of the truck-bolster for well-understood puroses.

A further object is to provide a rigid truckbolster and a body-bolster or transom supported thereby and hung so as to swing thereabove.

Another object of the invention is to provide a rigid truck-bolster having a transom or body-bolster carrier thereon in which the body-bolster or transom is hung.

Other objects and advantages, as well as the novel details of construction, will be I more specifically described hereinafter, it being understood that changes in form, proportion, and minor details of construction may be resorted to without materially departing from the spirit of the invention or sacrificing any of the advantages thereof.

In the preferred form of my invention (shown in Figs. 1, 2, 3) I have illustrated the truck-bolster 1 having near each end a guideway 2 to receive a'retainer 3 for the antifriction devices 1, (illustrated as rollers,) which antifriction devices are interposed between the top of the bolster 1 and the bottom of a carrier 5, whereby the carrier will be permitted to have a transverse movement with respect to the truck-bolster. In the form illustrated in Figs. 1 to 3 each carrier is shown as having a base with upstanding side walls 6, each side wall having a bearing 7 in the upper end thereof. These bearings 7 are designed for the purpose of receiving a hanger for the transom or body-bolster, whereby the transom or body-bolster will be permitted to swing. The hanger is illustrated as comprising a rock-shaft 8, received by the bearing 7 and having depending arms 9 with tcrminally-disposed outwardly-projecting journals 10 engaging bearings 11 at the bottom of the recesses 12 in the body-bolster or transom 13, into which recesses the carriers and hangers project. By this construction the bearings for the rock-shaft and its journals will be protected from deterioration on account of varying atmospheric conditions. I prefer to make the truck-bolster of the rigid type, and intermediate its ends I prefer to provide an elongated opening 14, into which projects the pivot-pin 15, carried by the body bolster or transom 13. By the term rigid truck-bolster I mean a truck-bolster which is held against longitudinal and transverse movement, but not necessarily against vertical movement, for generally I prefer to have the truck-bolster seated on springs in the us ual manner, so that it may be permitted to have vertical movement with respect to the truck.

The structure just described will permit the carrier to have a transverse movement 'with respect to the rigid truck-bolster and will also permit a swinging movement of the transom or body-bolster across the path of movement of the carrier, and any tendency of the carrier to move other than transversely of the truck-bolster will be avoided by the upstanding stops 16 on either side of the carrier and which may be formed rigid with the truck-bolster 1. By hanging the transom on the carrier so that the center of gravity of the hanger will be below the fulcrum oi the carrier the necessary swinging movement of the car-body will be permitted, and the return of the car to its normal position, so that the bearings in the carrier and transom or bodybolster will aline, will be assured as soon as the vibration of the car-body is relieved.

In Figs. 4 to 6 I have illustrated a slightlymodified form of my invention in which the carriers 5 are connected by a web 17 of channel construction, which web carries a flange pivot-pin-receiving opening 14, correspondmg to the opening 14, (illustrated in Fig. 1,) the pivot 15 of the body-bolster or transom 13 being received in said openin 14 Depending from the web 17 is a hollow pin 18, projecting through an opening in the top of the truck-bolster 1 whereby the support for the transom comprising the carriers 5 and their connecting-web is permitted to move on an are on the bolster 1 In the form illustrated in Figs. 4 to-6 the upstanding side walls 6 are sufficiently spaced apart to pass on the respective outer sides of the bolster 13, and the hanger shown in this form comprises trunnions 19, having depending arms 20, connected at their lower ends by a journal 21 received in bearings 22 in the lower edges of the body-bolster or transom 13 which body-bolster or transom is sufficiently narrow to permit its insertion between the arms 6.

In Fig. 7 a construction is illustrated quite similar to that illustrated in Figs. 4 to 6, except that the connecting-web 17 is illustrated as being a commerical channel which is riveted at its ends to the carriers 5 in any wellknown manner.

The operation of the mechanism described in the last four figures will be substantially the same as that applied to Figs. 1 to 3, except that in the construction shown in Figs. 4 to 7 neither of the carriers 5 will be permitted to move without imparting movement to the other. In the form illustrated in Figs. 4 to 6 the elongated opening 14 will perm1t a bolt to be passed throu h the car sills or floor down through the holIow pivotpin 18 without obstructing the swinging movement of the bolster 13.

I would have it understood that while I have illustrated the most convenient forms of truck and body bolsters I do not limit myself to the exact details of construction, because I am aware that many diflerent forms of bolster might be utilized without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is

1. The combination with a rigid truckbolster, of a body-bolster or transom swingingly supported near its respective ends by the rigid truck-bolster; substantially as described.

2. The combination with a rigid truck-bolster havim an elongated opening therein, of a body-b0 ster or transom above the rigid truck-bolster and having a king-pin projecting through the elongated opening, and means on the rigid truck-bolster for swingingly sup porting the body-bolster or transom above the same; substantially as described.

5. The combination with a rigid truck-bolster, of a carrier above the truck-bolster and capable of having transverse movement with respect to the truck-bolster, and devices engaging the carrier for swingingly supporting the car-body, said last-mentioned devices being movable in a direction at an angle to the movement of the carrier; substantially as described.
